Description

Technical Field

[0001] This utility model relates to the field of high temperature reverse bias testing, and more specifically, to a temperature control device for a high temperature reverse bias testing machine. Background Technology

[0002] Semiconductors are materials whose conductivity at room temperature falls between that of conductors and insulators. Semiconductors are widely used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, and high-power power conversion. Common semiconductor materials include silicon, germanium, and gallium arsenide, which require high-temperature, high-humidity reverse-bias testing before use. A high-temperature reverse-bias tester places the diode or other component under test, such as a diode or MOSFET, inside a high-temperature test chamber. The chamber temperature is raised to a set value, and a specific reverse DC voltage is applied to the component to test its reliability, while simultaneously detecting parameters such as high-temperature leakage current and voltage.

[0003] In the prior art, a temperature control device for a high-temperature reverse bias tester, with application number 202223227573.7, belongs to the field of electronic technology. This temperature control device for the high-temperature reverse bias tester, in order to cool and control the working chamber and maintain its temperature stability, includes a chiller installed on the working chamber. The working chamber and the chiller are interconnected, and both are connected to the chassis via electrical wires, allowing them to be regulated by the chassis. The chassis enables the chiller to cool the working chamber, stabilizing the temperature inside and ensuring normal operation. An opening and closing mechanism is also installed inside the working chamber, connecting it to the chiller. This mechanism prevents condensate from the chiller from entering the working chamber and causing damage.

[0004] The applicant's research revealed certain shortcomings in the aforementioned solution. While the device uses a baffle to block condensate, it cannot collect or treat the condensate. The baffle only provides basic obstruction and cannot effectively concentrate condensate to prevent accumulation during operation. Furthermore, significant time is required to treat the accumulated condensate on the baffle; otherwise, excessive condensate buildup may disrupt subsequent operations. Addressing these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temperature control device for a high-temperature reverse bias tester. The aim is to improve the device's ability to block condensate through a baffle. However, this device cannot collect and treat condensate. The baffle can only block condensate in a simple way and cannot concentrate condensate to prevent it from accumulating during operation. Furthermore, a lot of time needs to be spent on treating the condensate accumulated on the baffle afterward. Otherwise, a large amount of condensate accumulation may affect subsequent operations.

[0006] This utility model is implemented as follows: a temperature control device for a high-temperature reverse bias tester includes a chassis, a working chamber installed on the upper end of the chassis, the chassis and the working chamber being electrically connected, the working chamber being used for testing, a cooling mechanism installed at one end of the working chamber, a condensate guiding mechanism installed at the bottom end of the cooling mechanism, and a condensate collection mechanism detachably installed on one side of the condensate guiding mechanism.

[0007] In a preferred embodiment of this utility model, the cooling mechanism includes a refrigeration unit, which is connected and installed at the upper end of the working chamber. A connecting shell is installed at the inner end of the working chamber, penetrating the working chamber and communicating with the refrigeration unit. The connecting shell has a flow hole that narrows from top to bottom. A motor is installed at the upper end of the working chamber, and a lead screw is rotatably installed at the inner end of the working chamber. The lead screw is driven by the motor, and a moving plate is threaded onto the lead screw. The moving plate is slidably sleeved on the outside of the connecting shell. A filter screen is provided at the upper end of the connecting shell. Cooling is achieved by the refrigeration unit. Cold air enters the working chamber through the connecting shell and the flow hole. The motor drives the lead screw to move the moving plate and change the cooling airflow effect in conjunction with the flow hole. A condensate guiding mechanism and a condensate collecting mechanism block and collect condensate, preventing condensate from accumulating inside the working chamber, saving time for subsequent condensate treatment, and reducing the possibility of condensate accumulation affecting the operation of the working chamber.

[0008] In a preferred embodiment of this utility model, a limiting block is installed at the bottom end of the lead screw, a guide block is installed on one side of the moving plate, a guide groove is provided inside the working chamber and the guide block is slidably connected in the sliding groove, and a guide rod is installed at the bottom end of the working chamber. The guide rod slides through the moving plate, and the stability of the moving plate is enhanced by the limiting block and the guide rod.

[0009] In a preferred embodiment of this utility model, the condensate guiding mechanism includes a guide plate, which is connected and installed at the bottom of the connecting shell. The guide plate is provided with a guide groove, and a connecting pipe is connected to the bottom of the guide plate. A connecting sleeve is fixedly sleeved on the outer wall of the guide plate, and an mounting plate is installed at the bottom of the connecting sleeve. The mounting plate is provided with a connecting groove. The condensate collection mechanism includes a collection box, and a connecting block is installed on one side of the collection box. The connecting block is slidably connected to the connecting groove. The collection box is slidably connected to the connecting groove via the connecting block. Condensate is guided through the guide groove of the guide plate and sent into the collection box through the connecting pipe for collection.

[0010] In a preferred embodiment of this utility model, the connecting sleeve plate is provided with an installation groove, a threaded rod is rotatably installed inside the installation groove, the threaded rod is threadedly connected to a movable sleeve, the movable sleeve slides through the connecting groove and the installation groove, a fixing groove is provided on one side of the connecting block in cooperation with the movable sleeve, an auxiliary block is installed at one end of the movable sleeve, an auxiliary groove is provided inside the installation groove in cooperation with the auxiliary block, the auxiliary block is slidably connected to the auxiliary groove, the rotation of the threaded rod causes the movable sleeve to move, so that the movable sleeve limits the connecting block from the lateral direction, so that the connecting block is fixed again, and the condensate collection mechanism is installed.

[0011] In a preferred embodiment of this utility model, a rod is rotatably mounted inside the mounting groove, a worm is mounted at one end of the rod, and a worm wheel is fixedly sleeved on the outside of the threaded rod. The worm and the worm wheel are meshed together. Rotation of the rod causes the worm to drive the worm wheel to rotate, thereby causing the threaded rod to rotate. At the same time, the self-locking property of the worm prevents the threaded rod from rotating in the opposite direction, thus enhancing the installation stability of the device.

[0012] In a preferred embodiment of this utility model, the rod rotates through one end of the mounting plate, and an external support is installed at one end of the rod.

[0013] In a preferred embodiment of this utility model, the external support is configured as a rotating handle.

[0014] The beneficial effects of this utility model are as follows: The temperature control device for a high-temperature reverse bias tester obtained by the above design is used to cool the air through a refrigeration unit. The cold air enters the working chamber through the connecting shell and the flow hole. The moving plate moves through the motor-driven screw and changes the cooling air output effect in conjunction with the flow hole. The condensate is blocked and collected through the guide plate, connecting pipe and collection box to prevent the condensate from accumulating inside the working chamber. When the work is completed or too much condensate has accumulated, the condensate needs to be treated. The rod is rotated by the external holding object. The rotation of the rod causes the worm gear to drive the worm wheel to rotate, which in turn causes the threaded rod to rotate. The rotation of the threaded rod causes the moving sleeve to move, so that the moving sleeve no longer limits the connecting block from the side. The collection box can then be disassembled through the connecting block. After treatment, it can be reinstalled. The installation and disassembly are relatively convenient. This device, through a condensate guiding mechanism and a condensate collection mechanism, can effectively block and collect condensate, preventing condensate from accumulating inside the working chamber, saving time in subsequent condensate treatment, and reducing the possibility of condensate accumulation affecting the operation of the working chamber. The condensate guiding mechanism allows for convenient and quick installation and disassembly of the condensate collection mechanism, making operation convenient and saving time.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-4 The present invention provides a technical solution: a temperature control device for a high-temperature reverse bias tester, comprising a chassis 100, a working chamber 200 installed on the upper end of the chassis 100, the chassis 100 and the working chamber 200 being electrically connected, the working chamber 200 being used for testing, a cooling mechanism 300 being installed at one end of the working chamber 200, a condensate guiding mechanism 400 being installed at the bottom end of the cooling mechanism 300, and a condensate collection mechanism 500 being detachably installed on one side of the condensate guiding mechanism 400.

[0020] In some specific implementations, the cooling mechanism 300 includes a refrigeration unit 310, which is connected and installed at the upper end of the working chamber 200. A connecting shell 320 is installed at the inner end of the working chamber 200, penetrating the working chamber 200 and communicating with the refrigeration unit 310. The connecting shell 320 is provided with a flow hole 321, which narrows from top to bottom. A motor 330 is installed at the upper end of the working chamber 200, and a lead screw 340 is rotatably installed at the inner end of the working chamber 200. The lead screw 340 is driven by the motor 330, and a movable plate 350 is threadedly installed on the lead screw 340. The movable sleeve is located outside the connecting shell 320. A filter screen is provided at the upper end of the connecting shell 320. The cooling is achieved by the refrigeration unit 310. The cold air enters the working chamber 200 through the connecting shell 320 and the flow hole 321. The moving plate 350 moves by the motor 330 through the lead screw 340 and changes the cooling air output effect in conjunction with the flow hole 321. The condensate guiding mechanism 400 and the condensate collecting mechanism 500 block and collect the condensate to prevent the condensate from accumulating inside the working chamber 200, saving the time of subsequent condensate treatment and reducing the possibility of condensate accumulation affecting the operation of the working chamber 200.

[0021] In some specific implementations, a limiting block 341 is installed at the bottom of the lead screw 340, a guide block 351 is installed on one side of the moving plate 350, a guide groove is provided inside the working chamber 200 and the guide block 351 is slidably connected in the sliding groove, and a guide rod 360 is installed at the bottom of the working chamber 200. The guide rod 360 slides through the moving plate 350, and the stability of the moving plate 350 when moving is enhanced by the limiting block 341 and the guide rod 360.

[0022] In some specific implementations, the condensate guiding mechanism 400 includes a guide plate 420, which is connected to the bottom of the connecting shell 320. The guide plate 420 is provided with a guide groove 421, and a connecting pipe 430 is connected to the bottom of the guide plate 420. A connecting sleeve plate 410 is fixedly sleeved on the outer wall of the guide plate 420, and an mounting plate 440 is installed at the bottom of the connecting sleeve plate 410. The mounting plate 440 is provided with a connecting groove 441. The condensate collecting mechanism 500 includes a collecting box 510, and a connecting block 520 is installed on one side of the collecting box 510. The connecting block 520 is slidably connected to the connecting groove 441. The collecting box 510 is slidably connected to the connecting groove 441 through the connecting block 520. Condensate is guided through the guide groove 421 of the guide plate 420 and sent into the collecting box 510 through the connecting pipe 430 for condensate collection.

[0023] In some specific implementations, the connecting sleeve 410 is provided with an installation groove 442, and a threaded rod 450 is rotatably installed inside the installation groove 442. The threaded rod 450 is threadedly connected to a movable sleeve 470, which slides through the connecting groove 441 and the installation groove 442. A fixing groove is provided on one side of the connecting block 520 to cooperate with the movable sleeve 470. An auxiliary block 471 is installed at one end of the movable sleeve 470, and an auxiliary groove is provided inside the installation groove 442 to cooperate with the auxiliary block 471. The auxiliary block 471 is slidably connected to the auxiliary groove. The rotation of the threaded rod 450 causes the movable sleeve 470 to move, thereby limiting the connecting block 520 laterally and fixing the connecting block 520 again, thus completing the installation of the condensate collection mechanism 500.

[0024] In some specific implementations, a rod 480 is rotatably mounted inside the mounting groove 442, a worm 490 is mounted on one end of the rod 480, and a worm wheel 460 is fixedly sleeved on the outside of the threaded rod 450. The worm 490 and the worm wheel 460 are meshed together. The rotation of the rod 480 causes the worm 490 to drive the worm wheel 460 to rotate, which in turn causes the threaded rod 450 to rotate. At the same time, the self-locking property of the worm 490 prevents the threaded rod 450 from rotating in the opposite direction, thereby enhancing the installation stability of the device.

[0025] In some specific implementations, the rod 480 rotates through one end of the mounting plate 440, and an external support 481 is installed at one end of the rod 480.

[0026] In some specific implementations, the external holder 481 is configured as a rotating handle.

[0027] Working principle: During use, the refrigeration unit 310 provides cooling. The cold air enters the working chamber 200 through the connecting shell 320 and the flow hole 321. The motor 330 drives the lead screw 340 to move the moving plate 350, which, in conjunction with the flow hole 321, changes the cooling airflow effect. The guide plate 420, the connecting pipe 430, and the collection box 510 block and collect condensate, preventing condensate from accumulating inside the working chamber 200. When the work is completed or when too much condensate has accumulated, and condensate needs to be treated, the external support 481 rotates the rod 480. The rotation of the rod 480 causes the worm gear 490 to drive the worm wheel 460 to rotate, which in turn causes the threaded rod 450 to rotate. The rotation of the threaded rod 450 causes the moving sleeve 470 to move, so that the moving sleeve 470 no longer limits the connecting block 520 from the side. The collection box 510 can then be disassembled through the connecting block 520. After treatment, it can be reinstalled. The installation and disassembly are relatively convenient.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
